The browser extension previously known as GooglePreview.

SearchPreview is a Firefox browser extension that inserts preview images (thumbnails) of web sites and popularity ranks into the Google, Yahoo and Bing search results pages. Thumbnails are created and provided by SearchPreview servers.

Usage:

After installation restart your Firefox, and try a search on a Google search site or Yahoo.

To disable SearchPreview click on in the status bar (bottom right corner) -> click again to enable.

If you only see gray borders next to the search results, you may have the ' Redirect Remover' extension installed. In this case please add ' searchpreview.de' to white list of ' Redirect Remover' .
